One historian wrote that it “presaged urban combat as it was to be waged . . . throughout the remainder of the twentieth century.” A journalist said that it was “as though a Verdun had happened on the Seine” or “a Gettysburg was fought in Harlem.” International media compared the siege of one building where defenders made a desperate last stand to the Alamo.

It isn’t the Battle of Stalingrad. It isn’t Manila, Hue, Mogadishu, or Grozny. It is the 1937 Battle of Shanghai, one of the earliest major engagements of the Second Sino-Japanese War. Between them, the Republic of China and the Empire of Japan committed a million troops to the battle. It was fought over more than three months, for control of what was at the time the second-largest metropolis in Asia. And the city’s large foreign-controlled sectors made it an incredibly complex urban battlefield.

The seventeenth installment in MWI’s Urban Warfare Project Case Study Series examines the Battle of Shanghai, extracting its most important and enduring lessons—from the critical factor of legitimacy in a fight for a globally connected city to challenge of synchronizing combat power in complicated, often chaotic, urban conditions.
